Changes in the physicomechanical state of an elastic layer with memory of the shape under bending and heating

On the basis of the model proposed earlier by the authors, we determine the phase and stress state of a layer characterized by the direct martensite transformation occurring under bending followed by the reverse transformation in the process of heating. It is shown that the nonuniform residual stress state is formed in the layer as a result of changes in its phase composition. These stresses gradually decrease in the course of heating, which is explained by the recovery of the original phase state of the material of the layer.
